The Historic Old US 80 Bridge over the Gila River in Maricopa County, a 9-span steel truss structure originally constructed in 1927 as part of the “Coast-to-Coast” highway, is the longest structure of its type remaining in Arizona today.

The Historic Old US 80 Bridge over the Gila River in Maricopa County, a 9-span steel truss structure originally constructed in 1927 as part of the “Coast-to-Coast” highway, is the longest structure of its type remaining in Arizona today. Structural Grace, Inc. prepared a load rating per the AASHTO LRFR (Load and Resistance Factor Rating) method.

The load rating addressed truss members damaged by vehicle impacts, corroded anchorages, and bearings locked in place by corrosion. It also included recommendations to address these bridge deficiencies.

Structural Grace, Inc. provided construction surveying for the US60 to Loop 202 in Mesa, Arizona. This stretch of roadway included eight bridges, numerous walls, PCCP paving, drainage, ramps and arterials. Completed on time with zero error and 100% safety for tight tolerance and important detail motifs.

Structural Grace Inc. performed construction survey and layout for the Loop 202/I-10 three tier traffic interchange. The project encompassed two miles of reconstruction including a three tier stack, a TI at Chandler Boulevard, new alignment of SR202, box culverts, a pump station and moving 2 million cubic yards of earth!
